HazMat Fee

An item is classified as a dangerous good if our website displays Hazardous Material (HazMat) information for it. There is a HazMat shipping fee for each item that qualifies as a dangerous good, except in the following scenarios:

The shipment is processed through FedEx Ground under the Limited Quantity option.

Each bottle is packed as an Excepted Quantity, with a maximum of 1g for items in class 6.1 packing group I or II, and up to 25g for all other hazardous materials.

If shipping is charged to your FedEx account, the HazMat fee will be billed directly by the courier. Otherwise, the fee will be included on your invoice. To help you avoid the HazMat fee, we can package a 5g order of a class 6.1 packing group I or II material as five separate 1g units, and a 100g order of any other dangerous good as four 25g units. This packaging adjustment will be made unless you instruct otherwise on your purchase order. Below, you will find the fee schedule from FedEx for handling hazardous materials.

Description

DPEPO features a robust phosphine oxide scaffold with enhanced stability and controlled reactivity. This bench-stable ligand integrates seamlessly into palladium-catalyzed cross-coupling processes, delivering efficient transformations under mild conditions. Its electron-rich character promotes rapid oxidative addition and facilitates catalyst turnover in demanding synthetic sequences.

Application

DPEPO serves as a robust, bench-stable phosphine ligand enabling efficient cross-coupling reactions in palladium-catalyzed processes. Its electron-rich nature enhances reactivity in challenging couplings, while the diphenylphosphino and ethoxy groups provide excellent functional group tolerance and ease of purification. Widely used in Suzuki-Miyaura and Negishi transformations, DPEPO facilitates high-yielding reactions with broad substrate scope, making it a practical choice for synthetic chemists developing complex molecular architectures.
